Hi, @ifrountas @kevinfarrugia Is there any update on this issue? I'm also getting the same warning in Google Lighthouse.

It's easy enough to update the library to use passive listeners.

Let me research this more and I'll add if there is no drawback.

Hi, this is also getting flagged for us in PageSpeed Insights (https://pagespeed.web.dev/).

I noticed this working branch: https://github.com/NickPiscitelli/Glider.js/tree/passive-listeners.. In my limited testing this branch does seem to fix the issue.

Please can you provide an update.

Thanks.

Hello @NickPiscitelli, also getting this flagged. That same branch looks to work for us as well. Any development would be heavily appreciated.

This is now available as an option in 1.7.9 called `passiveListeners`; let me know if this works for you. I will look into making this the default but I have hesitations around suppressing the scrolling for horizontal wheels and need to look further into it.
